Typical waterproofing details of foundations above the roof slab shall be followed as per approved shop drawing.
Roof slab waterproofing details.
This is one of the common causes of flat roof waterproofing failure.
On completion of waterproofing membrane and before undertaking any further activity it shall be tested by plugging the outlets and flooding 50mm above the highest point by hose and leaving flooded for twenty four hours before draining off.
Winkler one is a high performance waterproofing solution for flat roofs that encompasses all the positive features of a liquid applied roof system.
Winkler one material cost may be higher than some liquid applied membranes however the labor cost to apply it is lowered due to the reduced time of application steps and the details treatment efficacy.
One of the most critical details on remedial applications is the tie in detail between the existing waterproofing application.
Unauthorized entry shall be restricted to the waterproofing areas.
Perimeter foundation insulation is required in colder climates to reduce the heat loss from a slab on grade to the below grade foundation wall.
When waterproofing concrete a topical sealer is applied to the surface of the concrete.
Large amount of water vapour can evaporate from reinforced concrete or a wet screed.
Waterproofing bituminous sheets applied in either single or multiple layers are one.
Topical sealers can be made from acrylic epoxy and polyurethane based materials.
The sealer is impermeable provided it is applied correctly and forms a waterproof membrane around the concrete preventing moisture from entering the concrete.
Once the waterproofing membrane is laid drying out of the structural slab will mostly take.
